My problem is solved. I performed this equation on the image..


(B1 le 0)*0+(B1 ge 10000)*1+(B1 gt 0 and B1 lt 10000)*float (b1)/10000


 


where;          


le  means less than or equal          


ge means greater than or equal          


gt  means greater than         


lt   means less than
